macbook air battery question

hypertc13 · Dec 17, 2012, 11:34 PM

My macbook air is about 14 months old. The battery has 336 cycles on it and my battery capacity is already at 77%. Aren't these suppose to hold 80% capacity after 1000 cycles?

Also every now and then I'll be doing something whether it be surfing the web or streaming music and applications pause and it says my hard drive is full and I must make room. Then I'll restart my computer and check how much space I have and it shows I have near 20 GB of space left on the ssd. Does anyone else ever experience this?

If you have Apple Care you could perhaps check it out with them, they might give you a solution?

If I had only 20 GB remaining free space, I would be shopping for a larger SSD. Especially if you have minimal memory installed, Virtual Memory can suck up a lot of storage space in a heartbeat.

My MBPro is used every day for the past two plus years, has 69 cycles and the battery remains at 96%. I guess it is all in how you use your machines.

So you never use it on battery power? I don't see how it's possible to use it every day for two years and only cycle 69 times unless it was rarely used on battery power.

How do you look up the number of cycles and percentage?
